Sure, but all ARM systems do this. Even the iPod 1G 11 years ago would lower the main clock and turn off the second core when it wasn't needed.

Whats interesting is if they've done a better job at optimizing their power consumption then Qualcomm, or if their 32nm HKMG has lower leakage then the TSMC's 28nm. The use of a different process and 4 weak cores veres 2 strong cores certainly gives them room to differentiate their design, and while Qualcomm's designs are usually faster then the Cortex series, they also tend to be a little more power hungry.

Yeah, not sure whats up with that. Either its BS or else maybe they were having trouble producing enough chips.
